VEHICLE-TANK CONSTRUCTION.

Specification of Letters Patent.

Patented. May 25, 1920.

To all whom it may concern:

Be it known that I, ANDREW A. KRAMER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Vehicle-Tank Construction; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked. thereon, which form a part of this specification.

This invention relates to tank vehicle con struction and one of the objects thereof is to provide a tank and support therefor whereby the jars and stresses imparted to the vehicle or support will be communicated to a part of the tank construction best adapted to absorb and resist them.

As is well known, an elongated, tubular tank is substantially a boX girder which carries the load (the liquid) within the confines of the girder and if the strains or shocks incident to the travel of the vehicle over an uneven road bed are communicated locally to the walls of the tank, distortion is liable to take place with resultant disadvantages.

I have provided means whereby the shocks and strains may be communicated to end sheets and partition sheets forming a part of the tank and I have provided bolsters adapted to be connected to said end sheets and partition sheets so that the shocks and strains will not be subjected to the tanlc walls.

1n the drawings,

Figure I is a vertical, longitudinal, sectional view through a tank constructed in accordance with my invention.

Fig. II is a cross sectional view on the line II-II of Fig. I.

Fig. 111 is an enlarged sectional view through the meeting edges of two tank sections, showing the bolster connection therefor.

Fig. 1V is a sectional view through a slightly modified form of support, and

Fig. V is a detail perspective view of one end of the bolster, showing means for adjusting it with respect to different widths of bodies.

Referring now to the drawings by numerals of reference:

1 designates alining tank sections, the section 1 being provided with end cover plates 3 and 1- corresponding to the end cover plates and 6 on the section 2, the plates 4: and 6 being shown as in abutting relation and extending beyond the perimeter of the respective tank sections 1 and 2 to provide flanges 7 and S, secured together by fastening devices illustrated as bolts 9. Depending flanges 10 and 11 respectively are provided on the lower edges of the end plates 3 and 5, which constitute the respective ends of the completed tank and by reference to Figs. 1 and 111, it will be observed that the end bolsters consisting of the angles 12 and 13 for the section 1 and 14C and 15 for the section 2 are spaced apart so as to clamp the respective flanges 10 and 11 between their vertical walls, the horizontal walls constituting bases which rest upon sills 15 and 16, shown as channels and constituting part of the frame of the vehicle. The flanges 7 and 8 are clamped between the vertical walls of similar angles to provide a bolster 17, as clearly seen in Fig. 1, so that" the tank is supported at its ends and at its intermediate point to the sills 15' and 16, the bolsters being fastened to the flanges by the fastening devices 9.

lVhen the parts are assembled as shown in Fig. 1, any shocks 0r strains communicated to the running gear of the vehicle will be transmitted to the sills 15 and 16 and absorbed by the bolsters and end sheets so as not to be communicated to the tank consisting of the members 1 and 2, which rest above the sills 15 and 16, as shown.

Instead of connecting the intermediate flanges 7 and 8 to angle irons, a central supporting plate 18 may be interposed between the inner end sections 4: and 6 and bolted thereto, as shown in Fig. IV. In this construction the intermediate plate .18 will extend downwardly below the bottom of the tank and be bent in the form of a flange 19, resting upon the sills 15 and 16 to which it may be secured by the fastening devices 20.

In Fig. V I have shown the bolster flanges 7 and 8 as carried by lateral flanges 21 and provided with a plurality of holes or openings 22 whereby the bolster is adapted to be secured to difi'erent widths of bodies by placing the bolts or fastening means to the particular hole registering with the side sill or beam of the body, as will be well understood. In the constructions in which the web or plate extends from the bolster between two alining sections, it may not be expedient under all conditions to extend the plate to the entire top of the tank, therefore, my invention contemplates a provision of means whereby the plate may extend only part way of the height of the tank instead of entirely to the top, as shown in Fig. 1V.

From the foregoing it will be apparent that the tank may be built up of a plurality of completed sections, each an inclosed compartment, and that these sections may be connected together by the bolsters which support them in an etlicient manner so that the strains and shocks above referred to will not be communicated to the tank walls.

What I claim and desire to secure by Letters-Patent is:

1. A tank comprising a plurality of complete, alining sections having end sheets extending beyond the walls of the sections, and bolsters connected to the extended portions of the end sheets of adjacent sections.

2. A tank comprising a plurality of complete, alining sections having end sheets extending beyond the walls of the sections to provide flanges and built-up bolsters bolted to the flanges on the end sheets of adjacent sections.

3. A tank comprising a plurality of complete, alining sections having end sheets eX- tending beyond the walls of the sections, and bolsters connected to the extended portions of the end sheets.

4t. A tank comprising a plurality of independent sections, having end sheets extending beyond the walls of the sections, a bolster, and means for securing the extended portions of the end sheets and the bolster together.

5. A tank comprising a plurality of complete, alining sections having end sheets extending beyond the walls oi the sections, channels having vertical flanges connected to the projecting portions of the end sheets, and longitudinal sills supporting the lateral flanges of the channels.

6. A tank comprising a tubular body portion having end sheets with downward flanges, and bolsters connected to the flanges of the end sheets.

7. A tank comprising a plurality of complete, alining sections having end sheets er;- tending beyond the walls of the sections, and bolsters extending to the extended portions of the end sheets of adjacent sections, said bolsters having lateral flanges provided with a plurality of holes near their respective ends whereby the bolsters will be adjustable with respect to the width of the body to which they are to be secured.

In testimony whereof I aflix my signature.

ANDREWV A. KRAMER.
